South Devon President, Ralph "Führer" Donnington, after Dante's father refuses to go through with plans to redevelop the Brigands' clubhouse in a lucrative property development scheme.
Dante manages to escape with his infant sister, is put under the wing of child psychologist Ross Johnson, and is questioned by police in an attempt to convict the Führer.
After moving in with a foster family, a Dutch Brigand attempts to murder Dante with a bomb inside the controller of a remote-controlled toy car on his birthday.
Ross and Neil reach out to CHERUB for their assistance and James, Lauren, and Dante are assigned to a mission to infiltrate the Brigands M.C.
James convinces mission controller Chloe Blake to allow him to purchase a motorcycle to aid him in getting closer to the Brigands.
The police, unaware of the CHERUB mission, move on the Brigands and their associates smuggling the weapons and thwart the surveillance operation.
